Each virtual machine (VM) is an independent system with an independent set of virtual hardware. Its main features are the following:
- A virtual machine resembles and works like a regular computer. It has its own virtual hardware. Software applications can run in virtual machines without any modifications or adjustment.
- Virtual machine configuration can be changed easily, for example, by adding new virtual disks or memory.
- Although virtual machines share physical hardware resources, they are fully isolated from each other (file system, processes, sysctl variables) and the compute node.
- A virtual machine can run any supported guest operating system.
The following table lists the current virtual machine configuration limits:
|CPU||8 virtual CPUs|
|Storage||15 volumes, 512 TiB each|
